STMicroelectronics TSZ901 High Accuracy/Bandwidth Zero Drift Op Amps
STMicroelectronics TSZ901 High Accuracy/Bandwidth Zero Drift Operational Amplifiers (Op Amps) are designed for precision applications requiring long-term stability and low noise. Featuring an ultra-low input offset voltage of just 3µV (maximum) and near-zero drift over temperature and time, the STMicro TSZ901 ensures consistent performance in demanding environments. The op amps offer a high bandwidth of 10MHz and a low input bias current of 200pA, making the devices ideal for sensor signal conditioning, medical instrumentation, and industrial control systems. Operating from a single supply voltage as low as 1.8V, the TSZ901 is well-suited for low-power designs, while rail-to-rail input and output architecture maximizes the dynamic range. With robust ESD protection and a compact footprint, the TSZ901 op amps deliver precision and reliability in space-constrained applications.
